Computer system with dual hosts

Abstract

A computer system with dual hosts is provided. The computer system includes a body, a first host, a second host and multiple peripheral devices. The first host and the second host are configured in the body, and the peripheral devices are coupled to the first host and the second host. When the first host starts, the peripheral devices are controlled by the first host. When the second host starts and the first host does not start, the peripheral devices are controlled by the second host.

1 . A computer system with dual hosts, comprising:
 a body;   a first host configured in the body;   a second host configured in the body; and   multiple peripheral devices coupled to the first host and the second host, respectively;   wherein the first host and the second host alternatively controls the peripheral devices according to a control priority.   
     
     
         2 . The computer system according to  claim 1 , further comprising:
 a switching unit configured in the body and coupled to the first host and the second host and the peripheral devices, for switching the control priority between the first host and the second host to make the first host or the second host control the peripheral devices.   
     
     
         3 . The computer system according to  claim 2 , wherein the switching unit is a multiplexer. 
     
     
         4 . The computer system according to  claim 2 , wherein the control priority is contained in a packet transmitted between the first host and the second host. 
     
     
         5 . The computer system according to  claim 4 , further comprising:
 a signal transmitting unit coupled to the first host and the second host, respectively, for transmitting the packet between the first host and the second host.   
     
     
         6 . The computer system according to  claim 2 , further comprising:
 an embedded control unit configured in the body and coupled to the first host, the second host and the switching unit, wherein the embedded control unit transmits a first control signal to the switching unit thereby makes the switching unit to choose the first host to control the peripheral devices; or transmits a second control signal to the switching unit thereby makes the switching unit to choose the second host to control the peripheral devices.   
     
     
         7 . The computer system according to  claim 6 , wherein the second host includes a touch panel, and the first host controls the touch panel via the embedded control unit. 
     
     
         8 . The computer system according to  claim 7 , wherein the touch panel is a displayer, and when the second host controls the peripheral device, the second host transmits images to the displayer. 
     
     
         9 . The computer system according to  claim 1 , wherein the peripheral device comprises a display unit, an audio input/output unit, a storage unit and a connecting port. 
     
     
         10 . The computer system according to  claim 1 , wherein the second host is embedded in the first host in a pluggable manner. 
     
     
         11 . The computer system according to  claim 1 , wherein the first host has an x86 architecture, and the second host has an advanced RISC machine (ARM) architecture.
